Appeal No. 2000-0341
Application No. 08/849,169
unit 12 takes place by the actual physical presence of the
card 14B, that is, the card is authorized by computer or
external unit 12 and then is presented to the reader 12 for a
new authorization for the operation of the vehicle. Thus, the
card has to be reauthorized by the external unit 12 physically
before a new authorized operation is reset. According to
the Examiner, this communication between external unit 12 and
the vehicle-mounted card reader unit 22 is replaced by a
wireless communication as taught by Uekusa. We note that the
Uekusa system does provide a teaching for communicating
between a mobile car and a stationary base station via a
wireless system. We do not find any impropriety, or
impermissible hindsight, in using the wireless communication
concept of Uekusa to substitute for the physical communication
between computer 12 and card reader 22 of Keating.
Appellants also argue, brief at page 10 that "Uekusa does
not use radio communication for this purpose [i.e., for the
purpose of using wireless communication with a base station so
that new release information could be updated without the user
being at the site of the renewal]." We are of the view that
Appellants are looking for a specific and explicit teaching
